HEADLIGHT-DIMMER.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed December 17, 1915. Serial No. 67,347.

To all whom it may concern Be it knownthat I, HARRY S. CLARK, a citizenof the United States, residing at Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inHeadlight- Dimmers, of which the following is a specification.

This invention relates to improvements in a headlight dimmer and has forits objects, to providea dimmer that is capable of being readilyattached to and detached from an ordinary headlight, to produce a dimmerthat is capable of being folded into a small space so that it-may bereadily carried in the pocket or elsewhere, to produce a dimmer thatwill illuminate objects near to they headlight,'to produce a dimmer thatis simple in construction and one that can be made at a very small cost,and, in general, to produce a dimmer of the character referred to.

This invention will be readily understood from the followingdescription, reference being had to the accompanying drawings, inwhich-- Figure 1 is a side elevation of an ordinary headlight with thedimer in position, part of the dimmer being broken away. Fig. 2 is asection on line 22 of Fig. 3. Fig. 3 is a front elevation of a dimmerin'folded position.

Referring to the drawings, 10 represents an ordinary headlight, to whichthe dimmer 11 is attached. Sewed to the rear portion of the dimmer is apiece of material, preferably cloth, as at 12. And also to the rearportion of the cloth is secured a cord 13. This cord is preferably anendless elastic band. The face 14 of the dimmer is made of celluloid'orother translucent material. This celluloid part is made up of twosectorlike pieces. These two pieces are held together by a strip ofcloth or other material as at 15. This cloth is stitched to thecelluloid. The cord 13, which extends com-. pletely around the headlightwhen applied thereto, is preferably placed in an opening formed bysewing the rearportion of the cloth 12 to itself.

When it is desired to attach a dimmer to an ordinary headlight thetvimsector-like venient and economical method of securing the dimertothe headlight. The stiffness of the celluloid keeps the dimmer inshape when 1n place. The c0rd.13 fits snugly in the crotch where thebody of the headlight and rim adjoin.

It will readily be seen that when the dimmer ls applied to the headlightthe light shmlng on the interior-of the dimmer from the headlight. willilluminate the face 14. Thls permits the light to shine in everydirectlon except directly backward. By this arrangement the grounddirectly below the headlight and all objects close to the headlight Willbe illuminated. This enables the driver to see objects close at handsuch as the curbing and obstacles in the road directly beneath thewheels.

accomplished in the desired manner. It will.

also be obvious that the details of construction may be modified withoutdeparting from the invention, especially as set forth in the broader ofthe appended claims. I do not, therefore, wish to be understood as beinglimited to the precise details of form and construction as shown.

I claim as my invention:

1. The combination of an automobile search lamp, and'a collapsiblecone-shaped translucent dimmer element detachably secured thereto.

2. The combination of an automobile head lamp, a cone-shaped foldabletranslucent dimming element, and meansfor securing said dimming elementover the face of said lamp .to completely cover the same, comprising aflexible border attached to the periphery of said dimming element andfitting over the rim of the lens opening of the lamp and havingassociated therewith a circumferential elastic member for holding therear edge of the said flexible border member in position over the rim ofsaid lamp.

3. A headlight dimmer for lamps, comprisinga border frame of materialformed and adapted to inclose the periphery of a lamp, and a dimmerelement connected with the border frame and arranged to completely coverthe face thereof.

4. A headlight dimmer for lamps, comprising a border adapted to inclosethe periphery of a lamp, an elastic element for securing the bordermaterial to the perlphery of the lamp, and a dimmer element secured tothe border material and arranged to completelg cover the face thereof.

5. headlight dimmer, comprising an element adapted to inclose the rim ofa head-' closing element, said translucent material adapted. to assume acone-like form when secured to the rim of the headlight.

6. A foldable headlight dimmer adapted to assume the shape of a conewhen applied.

'7. In a detachable headlight dimmer, a translucent face adapted tocover the face of a headlight, said translucent face being made of twosector-like pieces adapted to assume the shape of a cone when applied,an element secured to the translucent face and adapted to inclose the"rim of the headlight, and means for securing the element in positionwhen applied.

8. In a detachable headlight dimmer, a translucent member adapted tocover the front of a headlight, said translucent member being made ofsector-like pieces and adapted to assume the shape of a cone whenapplied, and an expansible element secured to the translucent member andadapted to inclose the rim of the headlight. I

9. A headlight dimmer, comprising an element adapted to be attached tothe rim of a headlight, and a dimmer element composed of sector-likepieces of translucent material adapted to be secured together and to thefirst mentioned element cone when applied and detachably secured to therim of the headlight.

12. In a detachable headlight dimmer, a dimming member arranged to coverthe face of the headlight, said dimming member being cone-like in shapewhen applied, and a fastening member secured to the dimming member andadapted tobe secured to the headlight. I

13. The combination of an automobile search lamp, and a flexibleresilient translucent curved dimmer element detachably secured theretoand adapted to assume a flat shape when detached from the search lamp.

14. The combination of an automobile head lamp, a translucent dimmingelement, and means for securing the dimming element to cover the face ofthe lamp, said dimming element being of sufiicient rigidity to causeportions thereof to project outwardly from the face of the lamp.
